BED-BOTTOM;

SPECIFICATION running part of Letters Patent No. 733,650, dated July 14, ieo; Application filed November 4, 1901. Serial No. 81,069. (No model.)

T0 all whom it may concern,.-

Be it known that I, WARDERVD. HUNT, a citizen of the United States of America,and a resi-V dent of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Bed-Bottoms, of which the following is a specification.

This invention relates to certain improvements in spring bed-bottoms, and more especially in that class of bed-bottoms or springmattresses which are formed from a spring structure covered over with a sheet of wovenwire fabric; and the object of the invention is to provide a bed-bottom of this general character of a strong, light, and durable nature and of a simple and inexpensive construction havingimproved means for holding the woven-wire covering-sheet in position upon the top of the structure.

Theinvention consists in certain novel features of the construction, combination, and arrangement of the several parts of the improved spring bed-bottom or mattress whereby certain important advantages are attained and the device is made simpler, cheaper, and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth. Y

The novel features of the invention will be carefully dened in the claims.

In the accompanying drawings, which serve to illustrate my invention, Figure 1 is a plan view showing a spring bed-bottom or mattress embodying my improvements. View showing a metal strip such as is employed for forming lthe end rail to which the Woven-wire covering-sheet is attached at its end. Fig. 3 is a sectional view taken transversely through said'strip and showing the first bend produced therein in the course of attaching the woven wire coveringsheet thereto. Fig. 4 is a view similar to Fig. 3, but showing the strip provided with its second bend. Fig. 5 is a view similar to Figs. 3 and 4, but showing the third bend produced in the metal strip. Fig. 6 is aview similar to Figs. 3, 4, and 5, but showing the metal strip provided with its fourth bend. Figs. 7 and 8 are views similar to Figs. 3 to 6, but

drawn to a larger scale and showing the metal rails 42 2.

Fig. 2 is aV strip provided with its fifth and sixth bends.

Fig. 9 is a side view, and Fig. l0 a plan view,

showing the clip for connecting the side and end rails ofthe spring structure. As shown in the views, the spring structure comprises atop frame of rectangular form produced from side rails l l and end Y A sheet 3, ofwoven-Wire fabric, is extended across this rectangular top frame, being attached at its ends to the end rails 2 2, as Will be hereinafter explained. For supporting the top frame helical springs 4 4 are employed, disposedrunifornily beneath the woven-Wire covering 3 and having their upper end coils held by intersecting cross-wires 5 5, which are extended in .two series across the top frame, each series being at right angles to the other. The ends otthese cross- Wires are connected, by means of loops orthe like, with the side and end rails l and 2 and serve to brace and strengthen the structure in a Well-known way.

At the corners of the rectangular top frame the side and end rails l and 2 thereof are connected together by means of clips or fastening means 6, herein shown as formed from sheet metal bent to shape and having tubu lar Shanks '7, in which the ends of the sidev rails 1 are engaged, and. also provided with lateral extensions 8 at their ends, in which Ythe extremities of the end rails 2 of the top frame are engaged. The extensions 8 of the clips are extended at right angles to the inner sides of the Shanks 7 thereof and are provided with upper and lower projecting parts or wings 9 9, adapted to be bent or clenched gated strip or piece of sheet metal, such as isv shown in detail in Fig. 2, this strip having a central crease or bend produced 'in it, as 95 shown at ct in Fig. 3 and indicated in dotted lines in Fig. 2, this central bend giving to the strip a V shapein cross-section, as clearly shown in Fig. 3. The end of the woven-wire covering-sheet 3 is then inserted between the two plies lO l0 produced by the central bend a in said strip, after which the two plies 10 l0 are pressed iiat upon each other, as indicated in Fig. 4, the end of the woven-wire sheet 3 being thereby fiattened out and held between said plies lO. A second central bend or crease l) is then produced in the folded strip 2, as indicated in Fig. 5, and the two plies ll ll produced in the strip by said bend or crease are also pressed fiat upon each other, as shown in Fig. 6, whereby it will be seen that the end of the woven-wire sheet 3 is securely held between the plies of the folded strip. A third and nal central bend or crease c is then produced in the folded strip, as shown in Fig. 7, and the two plies l2 12 thus formed are also pressed flat upon each other, as shown in Fig. S, whereby the folded metal strip is given a rounded shape in crosssection and is formed into substantially a straight metal rod or bar without sharp or rough projections and of considerable thickness and rigidity, such as is suitable for use as the end rail of the spring structure. The ends of the end rail or bar 2 thus produced are inserted in the sockets formed by the hollow extensions 8 of the clips 6, and when in place the projecting parts or wings 9 are pressed or clenched toward each other, as shown in Fig. 8, their inner adjacent edges engaging upon the upper and lower faces of the woven-wire covering-sheet 3 in such a way as to bind against the same, and thereby to securely hold the endrails 2 connected to the side rails l of the structure. The tubular Shanks 7 of the clips 6 are slitted along their inner sides, so that when slipped over the ends of the side rails l they may be pressed tightly upon said rails for holding them securely thereon.

The improved spring bed-bottom or mattress constructed as above described is of an extremely light, strong, and durable nature and combines all of the best advantages of an ordinary spring bed-bottom with those of the woven-wire covering-sheet, so that the device is of an extremely useful nature and may be readily cleaned. The ends of the woven-wire covering-sheet are also securely attached to the top frame of the structure and cannot be pulled loose therefrom, and since said ends are housed within the folds of the sheet-metal strips, of which the end rails 2 are formed, they present no rough or sharp edges or points to tear the bedding. The employment of the folded metal bars or rods as end rails for the spring structure also permits an economy in the manufacture, and since the extensions 8 are projected at right angles to the shanks 7 of the clips it will be seen that provision is made for extending the woven-wire covering-sheet entirely across the top frame of the mattress, as indicated in Fig. l. The edges of the woven-wire sheet 3 are also by preference attached at intervals to the side rails l of the top frame, and this attachment may be by means of loops 14, as indicated in Fig. 1, or otherwise. It will also be obvious from the above description that the improved bed-bottom or spring-mattress is capable of considerable modification without material departure from the principles and spirit of the invention, and for this reason I do not wish to be understood as limiting myself to the precise form and arrangement of the several parts of the device as herein set forth in carrying out my invention in practice.
